PEDAL.

SPECIFICATION forming part of Letters Patent No. 596,332, dated December 28, 1897. Application filed September 8, 1896. Serial No. 605,151. (No model.)

To @ZZ whom it may concern:

Be it 'known that I, ARTHUR L. MOORE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Pedals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the construction of ball-bearing pedals for foot-propelled vehicles.

The object of my invention is to provide a construction for ball-bearing pedals which shall be light and efficient and shall be composed of parts which may be easily and scribed, and pointed out definitely in the claim.

The drawing shows a perspective view, onehalf in section, of a pedal constructed according to myinvention.

.Referring to the parts by letters, A represents the pedal-frame7 which is a steel band having substantially parallel end pieces c, which end pieces are centrally perforated, the frame being in the particulars described substantially like the pedal-frames in coinmon use.

The sleeve B is or may be belled at each end to accommodate the cones on the spindle, and each end is internallythreaded. Each end is also provided with two external annular shoulders b. In the best construction these shoulders are formed by turning off the ends b, thereby reducing their diameter. The distance between these two shoulders is equal to the distance between the ends a of the pedal-frame. The reduced portions h are substantially as long as the ends of the pedalframe are thick, and they are shaped to iit the holes in the ends of the pedal-frames. These holes are preferably cylindrical, al`

l though they may have any desired shape.

nthe shoulders t.

To unite the sleeve and frame in the manner shown, the frame ends are sprung apart and the ends h of the sleeve inserted in the holes in said frame ends. The resiliency of the pedal-frame draws the ends tightly against It is not necessary to connect the frame and sleeve either by rivets, brazing, or any other means than the means described.

The spindle C has one cone c formed at its outer end and a reverse cone c near its inner end.

A tubular cap D, closed' at its outer end, is externally threaded and screws into the threaded outer end of the sleeve. It has an enlarged head (preferably button-shaped) at its outer end, which head is screwed up against the end of the frame and the end of the sleeve. This cap prevents the disconnection of the sleeve and pedal-frame at this end. It serves as an effectual dust-guard, and it is finished internally so as to cooperate with the cone c to form a raceway for the outer set of balls G.

E represents a centrally-perforatednut which is externally threaded and screws into the threaded inner end of the sleeve B. It is nished internally so as to cooperate with the cone c' to form a raceway for the inner set of balls G'. The adjustment of the bearing is effected by the manipulation of this nut, which may be fixed in the proper position by the screw F, which engages with its serrated iiange e, or by any other suitable means.

Having described my invention, I claim A pedal-frame composed of an integral closed band of resilient metal having parallel ends, said ends being substantially flat strips and each having a hole through it, in combination with an integral sleeve longer than the internal distance from one frame end to the other and having its ends substantially the same in circumference as said holes but being larger in circumference just back of said ends whereby external shoulders are formed, said sleeve having its ends projecting into said holes and`having its external shoulders in contact with the inner side of said frame ends, the said frame ends being held against said shoulders by the resiliency of said frame, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
